Yea, i'm with you. I worry about all the tiny little details and this type of app is wide open and my concern that i would get something wrong is near crippling my desire to help.
It's definitely my own neurosis here, but my desire to help is proportional to my desire to not hurt them. I'd love to help them, but i really don't want to mess something up for them either.
Well it’s entirely possible that they have to cross the street, so if nobody helps them on the app they just go ahead and pray for the best. But getting involved makes me feel responsible, not to mention the possible legal liability.
It's not like most of us are completely helpless when it comes to crossing streets. We know when it might be unsafe, and if a bus is approaching and you tell me to go, I wouldn't. But it might help a lot to actually reach the right street/find the second inaccessible traffic light/etc. You could also make sure that you describe the potential route to be taken, which might make it safer still. Sometimes a "A little left" or "You're turning onto another road" can be very helpful, which I assume was more or less the case. :)
I've had Be My Eyes installed on my phone for years but I never had the courage to answer a call. Part of it is that English is my second language, but fear of exposing someone to danger was even bigger. This situation sounds like the sum of all fears.
